The Casio AL-1000S was a follow-on to the original AL-1000, which was
Casio's first desktop programmable electronic calculator. The AL-1000S
adds the ability for the calculator to be connected to a modified
external electric typewriter to allow the calculator to be compeltely
operated from the typewriter, with all output printed by the typewriter.
For more information about the AL-1000, see the Old Calculator Web Museum
exhibit on the Commodore AL-1000,
